PingFor other uses, see Ping (disambiguation). ping in a Windows 2000 command windowPing is the name of a computer network tool used on TCP/IP networks (such as the Internet). It provides a basic test of whether a particular host is operating properly and is reachable on the network from the testing host. Ping provides estimates of the round-trip time and packet loss rate between hosts. It works by sending ICMP “echo request” packets to the target host and listening for replies (ICMP “echo response” packets). HistoryMike Muuss wrote the program in December, 1983, as a tool to troubleshoot odd behavior on an IP network. He named it after the pulses of sound made by a sonar, since its operation is analogous to active sonar in submarines, in which an operator issues a pulse of energy (a network packet) at the target, which then bounces from the target and is received by the operator. (Later David L. Mills provided a backronym, "Packet Internet Grouper (Groper)", also by other people "Packed Internet Gopher", after the small rodents ) The usefulness of ping in assisting the "diagnosis" of Internet connectivity issues was impaired from late in 2003, when a number of Internet Service Providers filtered out ICMP Type 8 (echo request) messages at their network boundaries. Internet worms such as Welchia flooded the Internet with ping requests as they sought to locate new hosts to infect, causing problems to routers across the Internet. Switches in Windows pingThe following switches are available to expand Ping's usefulness. The syntax is "ping -x <input>".
Switches in Linux pingThe following switches are available to expand Ping's usefulness. The syntax is "ping -x <input>".
OutputThe output of ping, and its cousins, generally consists of the packet size used, the host queried, the ICMP sequence number, the time to live, and the round-trip delay time, with all times given in milliseconds, and times below 10 milliseconds often having low accuracy. Below is a sample output where the wikipedia.com server is "pinged": $ ping -c 5 wikipedia.com PING wikipedia.com (130.94.122.195): 56 data bytes 64 bytes from 130.94.122.195: icmp_seq=0 ttl=235 time=284.3 ms 64 bytes from 130.94.122.195: icmp_seq=1 ttl=235 time=292.9 ms 64 bytes from 130.94.122.195: icmp_seq=2 ttl=235 time=289.7 ms 64 bytes from 130.94.122.195: icmp_seq=3 ttl=235 time=282.4 ms 64 bytes from 130.94.122.195: icmp_seq=4 ttl=235 time=272.0 ms The above sample is typical of ping on an operating system with a UNIX System V lineage. On a system with a BSD Unix lineage, ping traditionally only answers whether a host is ”alive” or not, but modern systems may provide a more System V–like output as shown above. The Windows ping utility returns the same information as the Unix implementations, albeit with different formatting. Pinging yahoo.comIn the early 1990s, many people began to ping yahoo.com when their internet connection seemed slow or dead. Many Internet Service Provider support technicians and simply tech-savvy individuals recommended pinging yahoo.com, creating this meme. It caught on, because in early 1990s, Yahoo was the primary hub of useful information and the domain name was already well known, and had a high uptime due to its then-unique use of Akamai load balancing. Today, other methods of checking connection speed and quality exist, such as traceroute or pinging other large sites such as google.com or cnn.com, but due to the meme Yahoo has remained popular.

The current Power Rangers DVD titles are:. In the early 1990s, many people began to ping yahoo.com when their internet connection seemed slow or dead. The ongoing concern over Power Rangers as a whole not being released on DVD Box sets has led to continued debate and frequent petitions. The Windows ping utility returns the same information as the Unix implementations, albeit with different formatting. There has been much criticism over the releases of these DVDs; only five volumes per season are distributed, which does not amount to the full length run, and so viewers have to rely on reruns to see any other episodes not currently available. On a system with a BSD Unix lineage, ping traditionally only answers whether a host is ”alive” or not, but modern systems may provide a more System V–like output as shown above. Buena Vista Home Entertainment is scheduled to release five new volumes of the upcoming season, Power Rangers: Mystic Force in 2006. The above sample is typical of ping on an operating system with a UNIX System V lineage. Internationally, however there have been additional DVD releases (such as Time Force and Wild Force in Germany) and as free DVDs attached to Jetix Magazine UK. Below is a sample output where the wikipedia.com server is "pinged":. Currently, there are only 18 DVD releases of Power Rangers in the USA (as listed below). The output of ping, and its cousins, generally consists of the packet size used, the host queried, the ICMP sequence number, the time to live, and the round-trip delay time, with all times given in milliseconds, and times below 10 milliseconds often having low accuracy. Contrary to wild Internet speculation, there have never been plans for a third Power Rangers movie. The syntax is "ping -x <input>". The Power Rangers series have also brought forth two movies. The following switches are available to expand Ping's usefulness. This fad-like popularization of martial arts in mainstream youth culture is often looked at as one of the reasons the McDojo has become somewhat of a prevalent phenomenon. The syntax is "ping -x <input>". Many also credit Power Rangers for an increased interest in the martial arts by suburban America. The following switches are available to expand Ping's usefulness. It would also cause them to lose revenue in toy and merchandising sales, which finance the shows. Internet worms such as Welchia flooded the Internet with ping requests as they sought to locate new hosts to infect, causing problems to routers across the Internet. However, whereas Power Rangers still appeals to older viewers, the show's producers feel that a more mature show might alienate their largest demographic—children. The usefulness of ping in assisting the "diagnosis" of Internet connectivity issues was impaired from late in 2003, when a number of Internet Service Providers filtered out ICMP Type 8 (echo request) messages at their network boundaries. This has led to some fans requesting that the tone and format of the show be changed in order to better suit its more mature audience. Mills provided a backronym, "Packet Internet Grouper (Groper)", also by other people "Packed Internet Gopher", after the small rodents ). However, since its release, the show has continued to evolve into a program that is enjoyed by more mature audiences, partly due to its aging original fans. (Later David L. When Power Rangers was first released it was classified as children's programming. He named it after the pulses of sound made by a sonar, since its operation is analogous to active sonar in submarines, in which an operator issues a pulse of energy (a network packet) at the target, which then bounces from the target and is received by the operator. However, Jetix in its British incarnation still issues a generic warning for the entire series that was used since the beginning of Power Rangers: In Space. Mike Muuss wrote the program in December, 1983, as a tool to troubleshoot odd behavior on an IP network. As a result, GMTV (who is still the analogue host in the UK) had to issue a warning at the end of an episode stating, "The Power Rangers are specially trained martial arts experts, so don't you copy them!" GMTV no longer issues this warning. . In the UK, the first incarnation sparked fears that kids would hurt themselves by recreating the moves in the series. It works by sending ICMP “echo request” packets to the target host and listening for replies (ICMP “echo response” packets). Team-ups between a current cast and the one before it occur almost annually now, but are generally superfluous to the larger storylines and are sometimes even considered out of continuity. Ping provides estimates of the round-trip time and packet loss rate between hosts. Subsequent series are able to start with new Rangers and villains annually without having to incorporate unresolved plot points from the previous season. It provides a basic test of whether a particular host is operating properly and is reachable on the network from the testing host. Space's finale, "Countdown to Destruction," acted as Power Rangers' version of Crisis on Infinite Earths, killing off or redeeming all of the older villains and largely cleaning up the existing continuity. Ping is the name of a computer network tool used on TCP/IP networks (such as the Internet). Veteran Rangers and villains also occasionally appeared after their stories had run through, most notably in Power Rangers: In Space, in which the central plot involved an attack on the entire universe. -W <timeout> - Time to wait for a response, in seconds. The first five years of the series featured ongoing storylines that carried through the different seasons, and retained most of its castmembers for several years. -w <deadline> - Specify a timeout, in seconds, before ping exits regardless of how many packets have been sent or received. The few-and-far-between links between the later series of Power Rangers are often resented by older fans of the show. -V - Show version and exit. Since then, no Asian-American actor or actress has played the Yellow Ranger, and no African-American has played the Black Ranger. -v - Verbose output. Amy Jo Johnson and Walter Emmanuel Jones appeared in the "1993" episode. -U - Print full user-to-user latency (the old behaviour). This was mentioned on VH1's I Love the 90s. -M <hint> - Select Path MTU Discovery strategy. This criticism was rendered moot when the two actors left the show halfway through Season Two and were replaced with an Asian American male as the Black Ranger, and an African American woman as the Yellow Ranger. -T <timestamp option> - Set special IP timestamp options. The first season of Power Rangers also drew criticism from some groups claiming that the Ranger colors were racist, specifically referring to Zack, the Black Ranger (played by African American actor Walter Emmanuel Jones) and Trini, the Yellow Ranger (played by Asian American actress Thuy Trang). -t <ttl> - Set the IP Time to Live. For a time Power Rangers was pulled from Malaysian television screens as the word "morphin" (in the phrase "It's Morphin Time!") sounded similar to the drug morphine, which is banned in Malaysia. -S <sndbuf> - Set socket sndbuf. Norway pulled the series as they believed that the series caused two boys to beat up a girl in 1993 (it was eventually found that the murder was unconnected to the series). -s <packetsize> - Specifies the number of data bytes to be sent. Later incarnations of Power Rangers often attempt to explain the actions of the Power Rangers, but many still believe that Power Rangers remains a series too violent for young children. -r - Bypass the normal routing tables and send directly to a host on an attached interface. In some cases, networks pulled Power Rangers from its lineup, citing such concerns. -R - Record route. Many critics of the early Power Rangers series claimed that the Power Rangers use unnecessary force to destroy their monsters, and often get into fights when better alternatives were available. -q - Quiet output. They were immediately replaced, to a negative effect on the show's ratings. -Q <tos> - Set Quality of Service -related bits in ICMP datagrams. John, Walter Emmanuel Jones and Thuy Trang left the series when none of their demands were met. -p <pattern> - You may specify up to 16 pad bytes to fill out the packet you send. When the series hit big time, Fox signed the show to a two-picture deal, and actors Austin St. -n - Numeric output only. The "Mighty Morphin" cast was bound to five-year contracts with no benefits and insultingly low pay (reportedly $500 US per week), which were non-negotiable. -L - Suppress loopback of multicast packets. Original Executive Producer Haim Saban was criticized heavily for his use of non-SAG actors, and the one-sided contracts that the actors were bound to for appearing on the show. -l <preload> - If preload is specified, ping sends that many packets not waiting for reply. In Power Rangers: Wild Force, the tenth incarnation of Power Rangers, this is taken to the next level, as ten Red Rangers teamed up in the episode "Forever Red." The only season not to feature this is Power Rangers: Ninja Storm, due to a shift back to non-SAG talent when production was moved to New Zealand. -I <interface address> - Set source address to specified interface address. A tradition in later incarnations is for two teams of Power Rangers to team up and take on a villain. -i <interval> - Wait interval seconds between sending each packet. In incarnations following Power Rangers: In Space, it is common for each incarnation to be separate, storywise, from previous incarnations. -f - Flood ping. Although much of the arsenal can also be found in Super Sentai, there are usually at least some that are not, generally added for the express purpose of marketing toys designed and sold by Bandai. -F <flow label> - Allocate and set 20 bit flow label on echo request packets. In some cases one Ranger may receive something that other Rangers may not have; an example of this is the Battlizer given to the Red Ranger of each series since Power Rangers: In Space. -d - Set the SO_DEBUG option on the socket being used. In many series, a Ranger is also given additional Zords or weapons. -c <count> - Stop after sending count ECHO_REQUEST packets. As the series progresses, one or more of the Rangers are also usually given a motorcycle for long-distance travel, as well as individual Zords. -B - Do not allow ping to change source address of probes. Each Ranger also has a secondary set of weapons that can often combine to form a larger weapon (usually a cannon). -b - Allow pinging a broadcast address. The arsenal available to the Power Rangers is also somewhat standardized: each Ranger is generally armed with a weapon such as a laser gun or a sword. -A - Adaptive ping. The penalty for disobeying these rules, at least in Mighty Morphin Power Rangers, would be the loss of their power. -a - Audible ping. The Power Rangers are also forbidden to disclose their identities to the general public, barring extenuating circumstances (although this rule was disregarded in Power Rangers: Lightspeed Rescue and Power Rangers: SPD). -w <timeout> - Timeout in milliseconds to wait for each reply. These include the Power Rangers being forbidden to use their Ranger powers for personal gain or for escalating a fight, explaining why the Rangers don't just step on the small monsters with their Megazord. -k <host-list> - Strict source route along host-list. Each team of Power Rangers, with few exceptions, obey a general set of conventions, outlined at the beginning of Mighty Morphin Power Rangers and implied, though not stated explicitly, throughout many of the other incarnations. -j <host-list> - Loose source route along host-list. The plot sequence is generally as follows:. -s <count> - Timestamp for count hops. A normal Power Rangers episode can be broken down into an everyplot. -r <count> - Record route for count hops. The team's costumes are nearly identical aside from color and perhaps a number designation; any additional Rangers will regularly have additional costume modifications. -v <TOS> - Type Of Service. There is usually no more than one Ranger of a given color on a team, but exceptions of this rule are generally given alternate names. -i <TTL> - Time To Live. Rangers may be named after their respective colors, such as Red Ranger, Blue Ranger, etc., but numbers or other names may also be used. -f - Set Don't Fragment flag in packet. Each Ranger's suit and energy spectrum will match a specific color, with red, yellow, and blue being joined by some combination of pink, green, black, or white. -l <size> - Send buffer size. Rangers regularly operate in teams of five, with a special sixth Ranger frequently rounding out the bunch; sometimes a core team of three will later be joined by additional Rangers. -n <count> - Number of echo requests to send. Rangers are known to "demorph" involuntarily due to powerful physical attacks. -a - Resolve addresses to hostnames. Helmets aside, the suits are donned and removed nearly instantaneously with a glow of light or some other effect. -t - Ping the specifed host until interrupted. Rangers appear to retain their original physiology beneath their suits when in morphed form, as Rangers' helmets have been seen removed or broken on numerous occasions, revealing his or her natural form underneath. A morphed Ranger generally possesses superhuman strength, durability, and hand-to-hand combat ability; unmorphed Rangers may possess other innate abilities (such as telepathy, superspeed, invisibility, etc.) which are usually not directly related to his or her Ranger powers. A Power Ranger is a person who "morphs" from a natural, unpowered form into a warrior clad in full-body, form-fitting spandex, as well as a plastic helmet with an opaque visor, which in many cases serves to protect his or her identity. Some seasons feature extremely large combinations of Zords known as "Ultrazords.". Often before a monster is defeated, it will grow into gigantic proportions, forcing the Power Rangers to use gigantic (bio)mechanical machines known as "Zords." In many cases, these can be combined to form a more advanced humanoid machines, known as a "Megazord." Because of the way Zords are combined, the Power Rangers may also use interchangeable parts to enhance their fighting power, or combine Megazords together to form larger Megazords. To activate these powers, the Power Rangers, "morph" by performing a standard action and reciting a "morphing call." Throughout the series, the Power Rangers learn the importance of teamwork and perseverance as they battle progressively more difficult monsters. Each Power Rangers season centers around a group of teenagers (age of actors actually varies from 18 to 23 years old), who gain super powers to fight various villains, ranging from demons to witches to aliens. . The show continued to air on the Fox Network until Fox Kids was dismantled in 2002, and has since aired on various Disney-owned stations. Power Rangers was officially purchased by Disney in 2001. Power Rangers was distributed by Saban Entertainment from 1993 until the end of 2001 and was broadcast on the Fox network. Due to the very Japanese nature of many of Sentai's stories and design, the American shows are always at least slightly changed to fit a Western audience. While the concept is based on the Super Sentai series of yearly serials, it is not an English dub of the original, but rather a 'new' production with English-speaking actors spliced in with the original Japanese footage to varying ratios. The show is directly tied into a vast merchandising empire largely owned by Japanese toy company Bandai. Power Rangers is an ongoing saga of television series about the epic adventures teenagers or 20-somethings who transform into the titular superheroes. There have been rare exceptions to this rule. Vice versa, Rangers cannot shoot at a growing monster. Power Rangers follows a few unofficial anime conventions, namely that a villain cannot shoot while Rangers are morphing or while a Megazord is forming. His colors were Green, White (Mighty Morphin' Power Rangers, Red Power Rangers Zeo and Power Rangers: Turbo, and his latest and presumably final color, Black Power Rangers: Dino Thunder.). Frank, who appeared in more episodes of the series than any other actor, is the only one to have appeared in five incarnations in the same role, and he has shared screen time with Rangers of each of the first thirteen different seasons. Tommy Oliver (Jason David Frank) is the only character to have worn four different colors as a Ranger. Kendrix appeared periodically to assist her replacement Karone, and was returned to life in the season finale of Lost Galaxy. Valerie Vernon, who played the character, collapsed on set and was diagnosed with leukemia, forcing her to leave the show. Kendrix from Power Rangers: Lost Galaxy was the first Power Ranger to die. This is one of the first children's television shows to include bleeped swear words, during the credits when outtakes were shown. Ninja Storm would be the first full Power Rangers season to feature a male Yellow Ranger and a female Blue Ranger, though the Alien Rangers miniseries had earlier featured a White female Ranger and a male Yellow Ranger. Stock footage of the Japanese series became confusing to even casual viewers, but was considered acceptable because the Yellow Ranger would be so inconspicuous among five or more Rangers. The Japanese Sentai series regularly switch between male and female Yellow Rangers, but as yellow is considered feminine in Western cultures, women were traditionally cast in the part for the Power Rangers adaptations regardless. Red, Blue, and Yellow are the only colors that have been a part of every Power Rangers team. 2002 episode "Forever Red" gathered many different cast members from the show to commemorate the tenth anniversary of the franchise.

Rangers are shown back in everyday life, having learned a life lesson which solves the earlier dispute. Rangers fight and defeat said giant minion, usually using a flashy trademark move. Optional: Rangers find that their current powers are insufficient to defeat monster and discover a new power, such as a Battlizer armor for the Red Ranger, a sixth Ranger, or a new Megazord. Evil enemy revives minion and makes minion grow to gigantic proportions, followed by Rangers summoning giant machines known as Zords and/or their combined form, the Megazord. Rangers defeat minions/footsoldiers. Rangers morph. Rangers fight minions/footsoldiers. Rangers are attacked by evil enemy's minions/footsoldiers. Rangers are seen in everyday life with a dispute to resolve. |
